This is alright, squid-2.5.STABLE14-4.el4 contains both security updates plus
something more and the swap of release times of these rpms was just a
coincidence. Hopefully, this won't be repeated in the future. I apologize for
any trouble that you might have because of this. However, since in the end,
there is no regression caused by all this, I'll close this bug report with the
resolution NOTABUG. If you feel this is still an issue, feel free to reopen this
bug. Thank you.
